Godin Multiac Spectrum SA

Aside from his Eric Clapton signature model Bellezza Nera, Roger Waters used the Godin Multiac Spectrum SA steel string guitar during The Wall Live tour (2010 - 2012). As Roger said "I love this guitar. I use it live on Hey You." Unfortunately, this song is entirely played behind the wall so we cannot see him actualy playing it. Hey You is notable for using a high strung "Nashville" tuning so perhaps this is how Roger's Godin is tuned.
He also uses the nylon string Godin Multiac ACS-SA on Good Bye Blue Sky. The natural high-gloss version of this guitar can be seen in the hands of G. E. Smith and David Kilminster when performing Is There Anybody Out There.
Godin Multiac Spectrum SA features a mahogany body design, ebony fingerboard, Seymour Duncan Lipstick pickup in the neck, custom Godin electronics along with separate tone and volume controls for the Lipstick pickup, as well as 13-pin capabilities for computer & synth access. Roger's guitar has a Black High-Gloss color.
Godin Multiac ACS-SA features a chambered maple body, cedar top, mahogany neck, and ebony fingerboard. The engine includes individual transducer saddles powered by a customized preamp system from the RMC Pickup Company. This system produces a hexaphonic output through a 13-pin connector enabling direct access to Roland GR-Series guitar synthesizers.
